Is It A Triangle? Or Is It A Diamond? by 

It’s a triangle, actually. This shot, taken looking up at Melbourne’s highest building, Eureka Tower, was taken in January 2010 under a clear blue sky that you can see faithfully reflected in the building’s facade. 1,678 views on 1 August 2014

The tower was opened in October 2006 and is located at 7 Riverside Quay, Southbank.

But the base of the triangle creates its own reflection and the composite shape actually creates an imperfect diamond.

The glass facade is a faithful mirror of the weather and in this case you can see I shot this under a flawless sky. It’s also interesting, I guess, to note that the pattern underneath the triangle is actually composed of a shapes that are simple variations of rectangles.

I do not crop, enhance or post-edit my images in any way. Shot with a Pentax K100D, using a Sigma 70-300mm lens. F6.7, 1/350 sec, ISO 200, focal length 108 mm.

    This is an amazing optical illusion,, I took some shots ,, but they sure dont look like this…. fantastic capture!

  • I knew you’d be familiar with the building, Linda. In this case, I just happened to look up and this unusual aspect caught my eye!

    Way better weather then, than when I went into the Eureka tower in November. (6th?) Did they find my sunglasses by the way? :-P

  • November was our hottest month in more than a century, but from memory the good weather began around the 9th or 10th. Yes, I heard a whisper that they’re waiting for you to reclaim the sunglasses!

    I like the different patterns being reflected in the glass panes. The white tiles sure don’t belong tot the building itself, but ‘stick’ on it visually. Keep looking up :-)

  • Thanks for the good advice, Peter. I will keep looking up at every building!

    hahah yeah, sometimes the “just happened to” shots are the best!!!

  • You’re so right, Linda. It’s when we look beyond or around the obvious …

    Haha… well they did contact me and said no… but I lost a few things on that trip, ah well.

    As for the heat, are you KIDDING me?!?!? :-P Seriously it was so cold. OK not like it is here at the moment, but there was no day when I could take off my jacket and some days where I needed my jumper too. The best day was the Monday then the Tuesday of the Melbourne cup, up until early evening when my friend lit up the BBQ and yep it started raining :-P I need to return anyway, if not for the sunglasses, then to just try and appreciate the place a little more :-)

  • Melbourne awaits your return …. and yes, the record-breaking hot spell must have started the moment your flight took off!

    what is the deal with the code here, I meant to write exclamation mark question mark explanation mark and so on… gah :-P

  • It always happens when people discuss Melbourne’s weather!

    Haha…. I think so… I took the Overland to Adelaide (well the replacement bus, as Telstra were having big problems in VIC) The second we got to Horsham, everything melted completely. Chocolate was liquid (that is just WRONG, planned or not!) and yeah… it was just weird that it went from fabulous weather in Sydney, grey as the train approached Melbourne then sunnier and sunnier the further we got away en route to Adelaide…

    Am singing Four Seasons In One Day now… a song forever associated in my head with Melbourne :-P

  • Yes, we always have jumpers in the boot of the car for the kids, even on a 40 degree day, because things change so dramatically.

    Great abstract shot!

  • Thanks very much, Shulie. It was completely unplanned, one of the many spontaneous shots I love to take!

    Nice lines and perspective…. A rhomboid perhaps

  • I thought about a rhombus, but the orientation didn’t seem exactly right. Thanks for reinforcing my opinion!
